Abstract
A motor shaft transmission supporting device comprises a front end cover (2), a motor shaft (1) and a single-row radial ball bearing (4) arranged between the front end cover and the motor shaft, and is characterized in that a single-row radial thrust ball bearing (3) is also arranged between the front end cover and the motor shaft. The utility model discloses a double-sleeve bearing in the front end housing, one set of single-row radial ball bearing need bear the radial power of motor, and the rotor gravity of motor when another set of single-row radial ball bearing need bear the anti-axial thrust and the vertical installation from the work built-in, and the normal use of motor can be guaranteed reliably to the axial that special service environment, radial force to the unification of double-sleeve bearing, has improved the life of motor greatly.
Description
Technical field
The utility model relates to a kind of motor shaft transmission bracing or strutting arrangement, belongs to the motor manufacturing technology field.
Background technology
All adopt a cover single-row radial ball bearing between the front end housing of general motor and the motor shaft, in order to bear the various mechanical device loads supporting with motor shaft, because the supporting machinery device not only will make bearing bear bigger radial load, also to bear certain axial force, and single-row radial ball bearing can only bearing radial force, can't bear certain axial force, so often burn out a bearing using in the short period, so that burn out motor itself, shortened motor useful life widely.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, compact conformation, can effectively improve the motor shaft transmission bracing or strutting arrangement of operational reliability.
The utility model is a motor shaft transmission bracing or strutting arrangement, comprises front end housing and motor shaft, places the single-row radial ball bearing between front end housing and the motor shaft, it is characterized in that also being equipped with simultaneously between described front end housing and the motor shaft single row angular contact ball bearing.
Can be interference fit between described single row angular contact ball bearing and single-row radial ball bearing and the motor shaft.
Can be interference fits between described single row angular contact ball bearing and single-row radial ball bearing and the front end housing.
Also can be provided with the cooperation seam on the described front end housing.Also can be provided with installing hole on the described front end housing.
The utility model is by the two cover bearings in the front end housing, one cover single-row radial ball bearing need bear the radially power of motor, another set of single row angular contact ball bearing need bear rotor from the motor when thrust and the vertical installation of the rotary-inversion axis in the working machine from gravity, two cover bearing unifications can be satisfied axial, the radial load of special environment for use, can guarantee the normal use of motor reliably, the useful life of having improved motor greatly.
Description of drawings
Accompanying drawing has provided structure cutaway view of the present utility model.
Among the figure: 1 is motor shaft, and 2 is front end housing, and 3 is single row angular contact ball bearing, and 4 is single-row radial ball bearing, and 5 for cooperating seam, and 6 is installing hole, and 7 is motor.
Embodiment
The utility model is mainly by the motor shaft 1 of translator 7, place the front end housing 2 of motor 7 one sides, place formations such as single-row radial ball bearing 4 between front end housing 2 and the motor shaft 1 and single row angular contact ball bearing 3, also be provided with the cooperation seam 5 of installing hole 6 and mechanical device on the front end housing 2.During use, mechanical device is installed on front end housing 2 outsides, along with the rotation of motor shaft 1, supporting mechanical device can be carried out the work thereupon.
Claims (5)
1. motor shaft transmission bracing or strutting arrangement, comprise front end housing (2) and motor shaft (1), place the single-row radial ball bearing (4) between front end housing and the motor shaft, it is characterized in that also being equipped with simultaneously between described front end housing and the motor shaft single row angular contact ball bearing (3).
2. by the described motor shaft transmission of claim 1 bracing or strutting arrangement, it is characterized in that can be interference fit between described single row angular contact ball bearing (3) and single-row radial ball bearing (4) and the motor shaft (1).
